Price Determination In A Competitive Market Flashcards
What does demand mean ?
Demand is the quantity of a good or service that consumers are able and willing to by at a given price during a given period of time
What does a demand curve show ?
A demand curve shows the inverse relationship between price and quantity demanded
What causes the demand shifts (PIRATES) ?
- Population
- Income
-Related goods - Advertising
- Tastes And Fashion
- Expectation
- Seasons
What is price elasticity of demand ?
PED = % change in demand / % change in price
What is elastic demand ?
- PED>1. A percentage change in prices will cause a large % change in quantity demanded
What is perfect elastic demand ?
Perfect elastic demand means that any change in price will cause the demand to fall to zero
What is inelastic demand (0<PED<1)?
This is when the percentage change in price will cause an even small percentage change in quantity demanded
What is perfectly inelastic demand (PED=0) ?
A change in price will have no effect on quantity demanded
What does unit elasticity of demand ?
This is when the size of % change in price is equal to % change in quantity demanded
Define income elasticity
Income elasticity shows how a demand of a good changes with changes in the real income
What is the equation of YED ?
YED = % change in quantity demanded / % change in price
What is the cross elasticity of demand ?
This the quantity demand of goods responds to a change in the price pf another good
XED (+ve) = substitiutes
XED (-ve) = complements
Define total revenue
Total Revenue = Price Per Unit x Quantity demand
